Ryan Giggs will know whether he is ready to succeed Louis van Gaal as Manchester United manager, according to former Red Devils team-mate Nemanja Vidic.

Van Gaal's position has come under increased scrutiny in recent weeks, with his assistant Giggs and former Chelsea boss Jose Mourinho the reported front-runners to replace him should the United board decide to act over the next few months.

Giggs, who enjoyed a glittering playing career with United, served as player-coach under David Moyes in the 2013-14 season and was interim manager following the Scot's dismissal prior to Van Gaal's appointment.

Vidic believes there would be merit in choosing either Giggs or Mourinho, and thinks the Welshman must have an 'honest conversation' with the United board in the event that Van Gaal leaves.

'I like the idea of Giggsy, but Mourinho has had success in the past,' the Serbian told BBC Sport.
